Comgall was a sixth-century Irish abbot and one of the founding fathers of early Irish monasticism. By tradition he was born around 510 to 520 in Dal nAraidi in Ulster, in the north of Ireland, and pursued his formation under several of the leading monastic teachers of the age before establishing his own community. His enduring achievement was the foundation of the monastery of Bangor on the southern shore of Belfast Lough, which became one of the most influential centers of learning and ascetic discipline in the early medieval Irish church.
Before founding Bangor, Comgall is said to have studied under a number of prominent Irish figures, among them Finnian of Movilla, Fintan of Clonenagh, and Ciaran of Clonmacnoise, and he was ordained deacon and priest. The monastery of Bangor was established by tradition no later than 552, though scholars variously place its foundation between 552 and 559. Under Comgall's governance the community grew large, and tradition holds that he oversaw Bangor together with other dependent houses, where the monks lived by manual labor and a rigorous ascetic regimen.
The rule that Comgall imposed at Bangor was austere: prayer and fasting were continual, food was scant and plain, and the chanting of the divine services held a prominent place in the monastic day. The monastery acquired a reputation as one of the foremost in Ireland and became a celebrated training ground for missionaries. The strictness of its discipline shaped a generation of monks who carried Irish monasticism across Britain and the European continent.
Comgall died, according to varying accounts, in 597 or 602. He is venerated as a pre-schism Western saint, and his feast is kept on May 10. His relics were preserved at Bangor until the Viking raids of the ninth century, when, in the course of Norse attacks on the monastery in the 820s, his shrine was seized and his relics scattered.
